SIAM will be reprinting Cornelius Lanczos' book on Linear
Differential Equations in our Classics in Applied
Mathematics series. We are looking for someone who has
a copy of the book and who would like to donate it to
SIAM--we will have to cut and paste the pages. In exchange,
SIAM will give two complimentary copies of the new edition.

Please contact Vickie Kearn, Publisher, SIAM, 3600
University City Science Center, Philadelphia, PA 19104-2688;

Subject: Sideways Heat Equation

A colleague and I are studying what might be called the "sideways"
heat equation: no initial data, ordinary boundary data at one end
of the spatial interval, overdetermined data (fcn & deriv) at the
other end. We are aware of two papers on numerical solution of
this problem, one by Ewing and Falk in Math. Comp.(1979), and one by
Monk in SIAM J. Num. Anal.(1986).

Is anyone aware of more recent work on this problem, especially
numerical methods? We have a decently working code, but before
we invest too much time we would like to know if we are re-inventing
the wheel here.

Subject: Integer Solutions to Linear Systems

A graph theory colleague has asked about numerical approximation of
solutions to linear systems Ax = b, where the solution x is
constrained to take on values only in a set of discrete values,
typically [0,1], but not always. This isn't an area I have any
knowledge of, so I thought I'd post a query. Does anybody have
any references for something like this?

Subject: Quadratic Programming Code


I am looking for a fast quadratic programming program (preferably in
FORTRAN) that can be used to solve very well behaved problems where the
number of constraints will almost never exceed 100 or 200. Speed is quite
important because the program has to be called many times as part of a
statistical estimation problem.
I appreciate any assitance you may be able to offer.

Subject: Report on HPCC Initiative


In 1994, congress mandated a National Academy of Sciences study of the
High Performance Computing and Communication Initiative to be delivered
to the President Clinton's Science Advisor and to the Secretary of
Defence by February 1, 1995. Congress wanted advice concerning the
goals, management, and progress of this five year initiative. The
Initiative plans call for federal expenditures of 1.1 billion dollars
in 1995.

We have completed the Study. You may be particularly interested in
Recommendation 3: Continue funding a strong experimental research
program in software and algorithms for parallel computing machines.

The report is called "Evolving the High Performance Computing and
Communications Initiative to support the Nation's Information
Infrastructure" It should be available from the National Academy
Press in Washington, D.C. in a few weeks. I do not know what its price
will be.

To order, I suggest you call the National Academy Press. The main number
for the Academy is (202) 334-2000. The Study was done under the aegis of
the Computer Science and Telecommunications Board. For information on
ordering the Study, you can also contact Leslie Wade, a member of
the Board's staff. Her address is

Subject: Formal Orthogonal Polynomials

Formal Orthogonal Polynomials

The connection between formal orthogonal polynomials (FOP), a
generalization of the usual ones, and the Lanczos' method for
solving systems of linear equations is known since Lanczos own
papers of 1950 and 1952. Nowadays, more and more people working
on Lanczos and affiliated methods refer to FOP.

I would like to point out that FOP are well-known for a long
time, for instance, to those working on Pad\'e approximants
and continued fractions. Here are some references, in chronological
order, that could be quoted.

These polynomials were in fact already treated in Chapter 11
* H.S. Wall, Analytic Theory of Continued Fractions, Van
Nostrand, Princeton, 1948.

They can also be found in
* E.L. Stiefel, Kernel polynomials in linear algebra and their
numerical applications, in "Further Contributions to the
Solution of Simultaneous Linear Equations and the Determina-
tion of Eigenvalues", NBS Appl. Math. Series, vol. 49,
1958, pp. 1-22.

It seems that one of the first papers entirely devoted to this
topics in relation with the Pad\'e table is
* P. Wynn, A general system of orthogonal polynomials,
Quart. J. Math. Oxford, (2) 18 (1967) 81-96.

Then, there are two papers by Gragg
* W.B. Gragg, The Pad\'e table and its relation to certain
algorithms of numerical analysis, SIAM Rev., 14 (1972)
* W.B. Gragg, Matrix interpretations and applications of the
continued fraction algorithm, Rocky Mt. J. Math.,
4 (1974) 213-225.

Let me mention my own book on the subject where the connection
between FOP, the Lanczos method and the topological epsilon-algorithm
is treated in detail
* C. Brezinski, Pad\'e-Type Approximation and General Orthogonal
Polynomials, ISNM vol. 50, Birkh\"auser, Basel, 1980.

The non-definite case was treated in the book by Draux where it
seems that the word "formal" first appeared
* A. Draux, Polyn\^omes Orthogonaux Formels, Applications,
LNM vol. 974, Springer-Verlag, Berlin, 1983.

More recently, the algebra of linear functionals on the space of
polynomials was formalized by Maroni in a series of papers
* P. Maroni, Sur quelques espaces de distributions qui sont des
formes lin\'eaires sur l'espace vectoriel des polyn\^omes, in
"Polyn\^omes Orthogonaux et Applications", C. Brezinski et al.
eds., LNM vol. 1171, Springer-Verlag, Berlin, 1985, pp; 184-194.
* P. Maroni, Prol\'egom\`enes \`a l'\'etude des polyn\^omes
orthogonaux, Ann. Mat. Pura ed Appl., 149 (1987) 165-184
* P. Maroni, Le calcul des formes lin\'eaires et les polyn\^omes
orthogonaux semi-classiques, in "Orthogonal Polynomials and
their Applications", M. Alfaro et al. eds., LNM vol. 1329,
Springer-Verlag, Berlin, 1988, pp. 279-288.
* P. Maroni, Une th\'eorie alg\'ebrique des polyn\^omes orthogonaux,
applications aux polyn\^omes semi-classiques, in "Orthogonal
Polynomials and their Applications", C. Brezinski et al. eds.,
J.C. Baltzer, Basel, 1991, pp. 95-130.

Biorthogonal polynomials also play a role in some generalizations
of the Lanczos method. They can be found in
* C. Brezinski, Biorthogonality and its Applications to Numerical
Analysis, Marcel Dekker, New York, 1992.

For the connection between FOP and the Lanczos method, two papers
by Gutknecht should be mentionned
* M.H. Gutknecht, A completed theory of the unsymmetric Lanczos
process and related algorithms, Part I, SIAM J. Matrix Anal.
Appl., 13 (1992) 594-639; Part II, idem, 15 (1994) 15-58.

There are, of course, many other sources that could have been
quoted but, for length reasons, they have not been given here.
